WATER-REPELLENT PAINTS AND ARTICLES WITH WATER-REPELLENT SURFACE

摘要

An article having a water-repellent surface layer containing a finely particulate material which has an average primary-article diameter of 1 to 200 nm and is sparingly soluble or insoluble in water, preferably a finely particulate metal oxide whose surface has been substantially fluorinated; a water-repellent coating material which is used for forming the water-repellent surface layer and contains the finely particulate material; and a method of imparting water repellency to an article which comprises either applying the coating material to the article or applying a coating resin and sprinkling the coating with the fine particles before the resin is solidified.
